  commit 918b8842a852e0e7446286f546724b1c63c56c66
  Author: Michal Orzel <michal.orzel@xxxxxxx>

      arm64: Change type of hsr, cpsr, spsr_el1 to uint64_t
      
      AArch64 registers are 64bit whereas AArch32 registers
      are 32bit or 64bit. MSR/MRS are expecting 64bit values thus
      we should get rid of helpers READ/WRITE_SYSREG32
      in favour of using READ/WRITE_SYSREG.
      We should also use register_t type when reading sysregs
      which can correspond to uint64_t or uint32_t.
      Even though many AArch64 registers have upper 32bit reserved
      it does not mean that they can't be widen in the future.
      
      Modify type of hsr, cpsr, spsr_el1 to uint64_t.
      Previously we relied on the padding after spsr_el1.
      As we removed the padding, modify the union to be 64bit so we don't 
corrupt spsr_fiq.
      No need to modify the assembly code because the accesses were based on 
64bit
      registers as there was a 32bit padding after spsr_el1.
      
      Remove 32bit padding in cpu_user_regs before spsr_fiq
      as it is no longer needed due to upper union being 64bit now.
      Add 64bit padding in cpu_user_regs before spsr_el1
      because the kernel frame should be 16-byte aligned.
      
      Change type of cpsr to uint64_t in the public outside interface
      "public/arch-arm.h" to allow ABI compatibility between 32bit and 64bit.
      Increment XEN_DOMCTL_INTERFACE_VERSION.
      
      Change type of cpsr to uint64_t in the public outside interface
      "public/vm_event.h" to allow ABI compatibility between 32bit and 64bit.
